Unable to attend

Pssst!

Don't tell anyone, but I've been invited to something secret. Can't tell you where. Or when. Can't tell you anything, it's a secret. Can't tell you who's invited me or what it's all about. Better not tell you what that badge is for or what that invitation card says. Can't tell you why I'm not able to go either. You might not believe me anyway. Can't say anything.
